Imr 8208 xbr
t*dbartell said: couldnt find a thread about it so excuse me if this is already mentioned http://accurateshooter.net/Blog/hodg8208xbr.jpg Hodgdon Powder Co. (http://hodgdon.com/index.html) has unveiled a brand new powder, IMR 8208 XBR (http://www.imrpowder.com/). From early reports, this is an exceptional new propellant that may change the way the game is played in short-range benchrest. According to Hodgdon, “IMR 8208 XBR is a remarkably advanced technology propellant” formulated for popular match, varmint and sniper rounds, including 223 Rem, 308 Win, 6mm PPC, 204 Ruger, 6mm BR, 22-250 Remington and similar calibers. We’re told the powder is being produced by ADI in Australia. IMR 8208 XBR is Consistent in All Conditions This short grain extruded rifle powder exhibits exceptional stability with virtually no change in velocity at temperatures ranging from -40 degrees F to 165+ degrees F. Lou Murdica, who helped develop this new powder, confirms that it is not temp-sensitive. Lou told us: “I have been shooting IMR 8208 XBR for over a year and I have done a lot of winning shooting it. One of the great things about this particular powder is, I always shoot the same load whether I shoot it in Florida or Phoenix AZ. I have never had to adjust for temperature or humidity.” That’s big news in the short-range BR game. Currently, most competitors must tailor their load to suit conditions. IMR 8208 XBR is Already Winning Matches Lou Murdica, one of the nation’s top BR shooters, won numerous matches with 8208 XBR in 2009, including the Heavy Varmint Grand Agg at the Cactus Classic. In August 2009, Jim Carmichel won the Heavy Varmint Grand Agg at the IBS Group Nationals. What is significant here is that Jim shot the exact same load of IMR 8208 XBR both days to win the event. That’s right–this powder requires far less “tuning” than most other powders currently used in short-range benchrest. Product Development and Performance Lou Murdica revealed some interesting facts about IMR 8208 XBR. Lou explained that the development team was initially trying to produce a propellant that would match the desireable characteristics of the “classic” T32 powder from the 1960s. In the process of developing a T-Powder clone, Lou says that the Hodgdon/IMR powder wizards came up with something even better: “We were originally pursuing a formula like T-Powder, but we came up with something a bit different. It was so good, and shot so well, that we didn’t want to lose it. It turned out that this stuff shot as well or better than the earlier T-clone mixtures and was incredibly stable.” http://accurateshooter.net/Blog/loumurd1x300.jpgLou continued: “I’ve shot a lot of T-Powder and it is sensitive in certain way. I feel this new powder is equal to, if not better than, a T-Powder clone because 8208 XBR is not sensitive. I can shoot the same load, at any location, in any temperature or humidity. Additionally, and this is very important — the new powder is very forgiving. It has a very broad accuracy window. If you’re shooting 30.0 grains in a 6 PPC successfully, we found you could go down to 29.8, or up to 30.2 and the accuracy was still there. You won’t see a change in group size. It has a very wide and forgiving load window.” [CAUTION: These charge weights may be excessive with your rifle and your bullets. Always start 10% low and work up.] The new powder is versatile and has plenty of energy. Lou tells us “8208 XBR is a great powder. With a 6 PPC shooting 68-grainers, I can get up into the 3500 fps range. And the powder will work with larger cases too. I’ve tried it with success in a 6BR with 105s and I think it will work in a Dasher or 6 BRX. I also shot it in a 22BR successfully.” Lou predicts that IMR 8208 XBR will have a big impact on the Benchrest game once it is widely available: “Once this powder gets in people’s hands I think you’re going to see GREAT things. It’s not finicky. It meters really well out of normal powder measures. It’s really stable. There are plusses all around. We’ll know within a year whether it becomes the powder to beat.” Lou is no longer involved in the sale or distribution of IMR 8208 XBR: “I’m not in it any more. I have to buy my powder like everyone else.” But he encourages all BR shooters to give it a try: “The powder is fantastic. I have been telling everyone to go to your powder dealers and order it. Buy a jug and shoot it.” Lou has high praise for the folks at Hodgdon: “You can’t say enough good things about Chris Hodgdon and Hodgdon’s willingness to develop this new powder. They’ve finally given us something we’ve really wanted and really needed. What they have done is great.” Product Availability — IMR 8208 XBR in Short Supply until 2010 IMR 8208 XBR will be available in 1-lb canisters and 8-lb kegs in 2010. Hodgdon has produced limited quantities already, and you may be able to find some 8208 XBR at popular vendors, such as Powder Valley (http://www.powdervalleyinc.com/), in early January, 2010. You’ll need to call around to see who has it.
Cy*N1de said: Great...another new elusive powder to chase after.
Myst*c Precision said: Don't worry, too fast for what we are after :-) Hodgdon has posted some load data for a variety of cartridges and it definitely favors the light bullet or small case. Ironically, velocities were not much better then standard powders. In fact, some examples were slower. All were loaded to SAAMI specs so there is room to hot rod. I would love for someone to put a strain guage on the PPC loads they are talking about and see just how hot it is. I am waiting for the super sized Re15 that will hopefully be developed in the near future. Same tech as the Re17 but in a faster burn rate ala Varget. Jerry

t*dbartell said: Ive been using it in 223 and 338F, works great. Will try it in my new 308 too. My boss uses it in his 300WSM as well with lighter loads
K*van said: Ive been using it in 223 and 338F, works great. Will try it in my new 308 too. My boss uses it in his 300WSM as well with lighter loads And would you know of a store that might happen to have some in stock ? ;)
Cy*N1de said: I still have 3# in my cupboard from the Kamloops Gun Show, I am waiting for it to double in price and then flog it for a 100% Profit. :D
P*thfinder said: I bought some from the shooter's den in Sudbury.
t*dbartell said: And would you know of a store that might happen to have some in stock ? ;) should work well in high velocity 303 loads with 150 grainers too :D and yes I know where there is some, currently $29.99/lb. Shipping approx $15 for 2-3 lbs
N*el said: Tod, Keep us posted on the 303 load development. Looks like it might be good in the 25 Rem and 250HP chambering too. Looks like you have found another great avatar photo as well.
W*ldfowlhunting said: My .308 with 44gr of the 8208 and the 155 Berger VLD, is a match made in heaven. The only other powder that I have tried that is close in comparison for groupings is the H4895.
Br*cecounty said: anybody tried this powder in 30-06 sized cases and larger yet , i know my 22-250 tikkia t3 lite loves it and 50 grainers

Hi Wildfowlhunting, have you been able to chrony the load? can you also give particulars of your rifle. barrel length, twist.? Trevor
W*ldfowlhunting said: Hi Wildfowlhunting, have you been able to chrony the load? can you also give particulars of your rifle. barrel length, twist.? Trevor I have a Styer SSG P2 in .308. The barrel is cold hammer forged and shrunk into the receiver for a barrel length of 26". The twist is 1 in 12 with 4 grooves. I was fortunate to be at the range when another shooter was using her chrony, she was kind enough to allow me to test mine. The shot was chrony'd at 2887 FPS, and that was with the 8208. I have not chrony'd the H4895.
n*tsorichguy said: I figgured I would revive this thread..... I read an artical in Gun World Magazine (Dec 2010). He had favorable results with XBR in .204 Ruger, 22-250, 6mmBR & 308. From -38f to + 90f the writer saw very little differance in velocity and no noticeable increase in group size. He did state that some of the velocities he saw were a bit slower than some other loads he has used, but all loads were consistant despite huge swings in temps tested in. My self I was thinking that I wouldn't mind giving up even 150 or 200 fps if I had a load that would work from -25 to +30 c........ Hogdons web site has loads for all the rifle cal I have in my safe, I was thinking I should pick up a lb or 2, see if it lives up to the hype........ Has anyone else had any luck with this powder?
L*ngshot said: I have some sitting on my shelf but haven't been able to give it a go yet. Some guys have had good results with it in their 6xcs which is where I will probably give it a shot.
n*neck180 said: I have done some testing with my 204 Ruger,nothing spectacular yet..
P*thfinder said: My self I was thinking that I wouldn't mind giving up even 150 or 200 fps if I had a load that would work from -25 to +30 c........ That's also my thinking, Im happy with 3550 or 3600 fps with 55 gr bullets if I can have the POI all year round.
w*rrenb said: Anyone tried this in the 223 with the heavier 69 to 80 grainer bullets?
t*dbartell said: Ive only used it up to 60 grainers in my 223, will try it with 77's when I get some. Im going to also try it in my new 17 Fireball (aka Mach IV). It worked great in my 308 and 303, wonderful powder IMO
w*rrenb said: I picked up 2 pounds and might try it with the 155 grn VLDs. I want to try it in the 223 with 80 grain SMKs but I think it might be too fast for that?
p*rple said: Wow, yet another "miracle powder".w:h: A new one seems to pop up about every 5 yrs or so. I remember all the clang and clamour over Varget about 16 yrs ago. It is good, but it did'nt make others like 4895, 4064, or 3031 any worse in the same cartridges.;)
w*rrenb said: Difference is, this one is supposed to be temp stable (like varget) and it meters well. Varget don't meter too bad but it ain't no BLC2 (flows like water). :D
p*c11 said: Can anyone post up who currently has some of this in stock? Mike
n*tsorichguy said: My local g-store has some in stock....... Shipping would be spendy....... :(
Ch*ckbuster said: The Shooter's Den in Sudbury has some. Give Dennis a call and he'll ship anywhere in the country...anytime I'm in there, he seems to be sending something to someone somewhere in the country.

I am getting very good groups with 28gr of Varget in my 204 Ruger, but not all in the same hole, perhaps it will be the magic elixir... FS
KDX said: That is a very nice 200 yard group. I wish I could do the same at 100. What are the rifle specs?

P*thfinder said: Ive got a bunch loaded for workup in my 22-250 . According to hodgdon I should be in the Hight 3700's with 55 gr. bullets. It will be interesting to note the velocities at -20C and again at 20 C . Just need a bit of time and for someone to plow a way into the Range !

*rchie_james_c said: Just need a bit of time and for someone to plow a way into the Range ! You aint lyin'. I went and worked up some loads for my .260 today...12" of snow and the thermometer read -13 C :O . I plan to see what i can do with 8208XBR, H4350 and Varget this winter and then compare the winter load in the summer :) .
r*mfiremac said: Careful shooting winter loads in summer... I cooked up some Varget loads last winter that showed pressure signs when I brought the remainder of them out for use in the spring- just a heads up.
P*thfinder said: I usually dont' work up loads the winter for that reason.....If this powder is so stable than I should be able to use the same load spanning a 40 C change. I temporarily froze bolt in a rifle on a hot day years ago before I knew better...RL-22 is not very stable.....found out the hard way.
*rchie_james_c said: Im aware guys, what I should have said was work up my winter loads, chrony them. Then work up to the same loads but in summer conditions to compare. Not just chamber my max winter loaded round in the summer and see what happens...work up as normal and compare to my winter data :)

How do you like your 17 so far? I need to take mine out for a drive and get re-acquainted with it.
t*dbartell said: I love it! whacked a yotie last week. Accurate and alot of fun to shoot
w*rrenb said: I finally tried IMR XBR 8028 today in my 223. :D Not great conditions -6 without wind chill. Head wind switching to the an east wind. I had already been shooting 308 and 223 for a good hour so by this time I was becoming a bit of a baby trying these loads. This is using 69 grain SMKs. I hope somebody finds it useful. Had the following 6 loads to try : 22.5 grs @ 4 shots group = .434 22.9 grs @ 5 shots group = .524 23.2 grs @ 3 shots group = 0.218 (I bolloxed 1 shot ignore as see fit) 23.5 @ 4 shots group = 0.320 23.8 @ 5 shots group = 0.341 24.0 @ 5 shots group = 0.341
KDX said: I love it! whacked a yotie last week. Accurate and alot of fun to shoot What was the distance? From what I've read 300yds isn't too much with the proper shot placement. I like the low recoil and relative quietness of the round. I was hesitant to jump into this caliber but decided to after doing a fair bit of research. I think if more people would put aside their bias and try the smaller calibers, they would find a whole new level of fun in their shooting/hunting experience. Cheap shooting too which is a plus for me.:D
P*thfinder said: Finally got out for some quick work up testing. (22-250 , 55 grain bullet) conditions were -10 or -19 with wind chill yesterday. I worked up to to the max load which was 35.8 gr. (according to hodgdon data) if I recall correctly and I fired a 3 shot group with that combination. (and a few other groups below) group size @ 100 yards was .549 and avg MV was 3750 fps. Not a low pressure load but no major pressure indicators yet. Ill be loading more and will shoot some 5 shot groups but its looking good so far. case: winchester primer: wlr bullet: 55 grain sierra blitz seat at 2.45" rifle: Rem 700 Varmint 24" barrel.
N*rmB said: Just a note on Windchill Equivalent Temperature. A warm body can't be cooled below ambient temperature ( -10 in this case). The rate at which it cools to -10 in the wind can be quoted as an equivalent temperature in still air (-19 in this case). Only warm bodies like you, radiators, bullets in your pocket are affected by windchill. Warm bodies cool to ambient temperature and no more. Windchill is really a cooling rate expressed in watts/sq meter. NormB
P*thfinder said: true. Im only noting it as -10 for my actual reloading records .

P*thfinder said: some good notes here about 204 and 8208......hmmm maybe I need a .204 http://www.accurateshooter.com/forum/index.php?topic=3745623.0
d*sker said: In 204 they did not show volicity with the XBR are they able to keep the speed up with it?
M*nitobahunter said: If you check out the hodgdon site, it shows 8208 has the top velocity in the lighter bullets and about even with other powders with heavier bullets.

PP. w:h: I've finally settled on 8208 for my M14. Went back & forwards a few times. With the internals swapped the gas system seems to really work well with it. It took some fiddling around to find it. XXX Gas piston, USGI spring, XXX spring guide and recoil buffer. Load: .308 Winchester brass, chamber formed and neck sized. Case trim to 2.007/chamfered/pp cleaned. CCI primer seated at 4-7. 150gr Hornady bullet 44 grains of 8208 XBR. Light to moderate crimp. It's very accurate with this load and the gas system operates slick as snot. Best results are obtained with neck sizing. Initial loads with new factory brass are way off no matter what the powder. Post neck sizing accuracy improves by 50%, each subsequent sizing obtaining slightly better results as you progress down the line. 8208 seems indifferent to hot & cold, meters very well and has the consistency of course sand. It's also the same price as the other powders. Hope that helps.
